Abstract

The present invention relates to a force-induced hydraulic chamber-amplified downdraught engine which belongs to the field of hydraulic drive mechanisms. Staged energy amplification is carried out through a multi-stage machine set composed of a hydraulic motor and an oil pump which have the same power. After energy diffluence, a part of energy enters the hydraulic motor to do work to as to convert pressure energy into mechanical energy, the other part flows back to an energy accumulator and uses the energy of the energy accumulator as a power source to start the engine so that the engine can continuously output energy and do work on a working surface. The engine can substitute various resources and other engines in a wide range and is an energy-saving product.

Description

Inner rib tubes type water heater

The present invention relates to a kind of technological improvement of the displacement type water heater by shell and tube heat exchange body and burner be combined into.

Popular for many years various fuel oils, the displacement type water heater of combustion gas (also claiming " miniature boiler "), majority be with the tubular heat exchanger of steel as wherein heat exchange body, adopt light pipe (the pipe inside and outside wall all is smooth faces of cylinder) as the tube bank in the heat exchange body; Constituting the moving space of hot flame plume by the internal face of tube bank is the tube side space, by the internal face of the outside wall surface of tube bank and heat exchange body case and on the forward surface of lower perforated plate to constitute water space capacity be the shell side space.Not only exothermic coefficient is little but also heat exchange area is little owing to tube side one side, then must satisfy the heat exchange effect of requirement with the volume that increases tube bank quantity, increase heat exchange body.Thereby formed that the heat exchange body that falls behind is not complementary with advanced burner, " miniature boiler " real common fault of thick heaviness still, the living conditions of this and China general family in cities and towns are incompatible; And the heat exchange effect also remains to be improved.

Purpose of the present invention, be to create the heat exchange body that a kind of structure is light and handy, volume is small and exquisite, have good heat exchange effect, itself and advanced burner are complementary, adapt to China's general family living conditions and ability to shoulder economically, can be used for that heating is had a bath and the displacement type water heater of boiling water i.e. " miniature boiler " and constitute.

Realize purpose of the present invention, depend on the technical scheme of following improvement.

1, displacement type water heater of the present invention is formed by combining by shell and tube heat exchange body and burner, shell and tube heat exchange system is wherein formed by structures such as tube bank, heat exchange body case, lower perforated plate, upper perforated plate, admitting pipe joint, titting water outlet in the heat exchange body; And have following feature:

The bottom of this shell and tube heat exchange body is to be the combustion chamber of wall with the water jacket samdwich, combustion chamber system by inner layer wall and outer wall constituted, the top of combustion chamber is lower perforated plate, be shaped on the plate face through hole that can match with the lower port of tube bank on the lower perforated plate, the quantity of this plate face through hole equates with the quantity of tube bank; Plate face number of openings on plate face through hole on the upper perforated plate and the lower perforated plate equates and is corresponding one by one; The upper and lower port of many tube banks in this shell and tube heat exchange body is fixed on respectively in the plate face through hole of upper perforated plate and the plate face through hole on the lower perforated plate correspondingly; Being shaped on some and tube wall on the internal face of tube bank is the fin of one.

The advantage of this technical scheme is: be the combustion chamber of wall can avoid the burning heatsink transverse of interior flame with the water jacket samdwich, the internal-rib tube bank has enlarged the area of tube side one side in the heat exchange body, has promptly enlarged the effective heat exchange area of heat exchange body.

2, adopt the aluminum alloy materials of lightweight to make the heat exchange body, the internal-rib that wherein has fin is restrained an extrusion modling of available aluminium alloy, the radial height of the inner rib plate of its shaping efficiency and acquisition, be with other metals and other processes can not be when.Thereby not only can improve the heat conductivility of heat exchange interface, the water-fast erosion performance of raising heat exchange body, and can simplified manufacturing technique, increase considerably the effective heat exchange area of tube side one side, reach and can satisfy the purpose that the heat exchange effect can alleviate heat exchange body own wt again.

3, be round tube as the inner rib aluminum type tube as tube bank, available core pipe is occupied the shaft space of tube bank, forces the hot flame cigarette to flow along between internal face of restraining and inner rib plate, with the exothermic coefficient of remarkable enhancing tube side one side, promotes high efficient heat exchanging.
